Development Dictionaries for the wwPDB Deposition and
Annotation System

EMDataBank partners PDBe and RCSB are in the process of
developing 3DEM joint map + model deposition capability
within new Worldwide Protein Data Bank (wwPDB) deposition
and annotation (D&A) system. The D&A system
will become available for 3DEM depositions in mid-2014. The
aim of the D&A system is to facilitate the process of
deposition of biomacromolecular structure data by all major
experimental methods, including hybrid methods, and to
provide tools for validation. The underlying data model used
to describe EM experiments in the new system has been
expanded to capture the important aspects of the various EM
methodologies and new developments in this rapidly evolving
field. The updated data model is implemented in both
mmCIF and xml.
